   1 # This Makefile fragment (since dpkg 1.19.0) defines the following variables
   2 # for host tools:
   3 #
   4 #   AS: assembler (since dpkg 1.19.1).
   5 #   CPP: C preprocessor.
   6 #   CC: C compiler.
   7 #   CXX: C++ compiler.
   8 #   OBJC: Objective C compiler.
   9 #   OBJCXX: Objective C++ compiler.
  10 #   F77: Fortran 77 compiler.
  11 #   FC: Fortran 9x compiler.
  12 #   LD: linker.
  13 #   STRIP: strip objects (since dpkg 1.19.1).
  14 #   OBJCOPY: copy objects (since dpkg 1.19.1).
  15 #   OBJDUMP: dump objects (since dpkg 1.19.1).
  16 #   NM: names lister (since dpkg 1.19.1).
  17 #   AR: archiver (since dpkg 1.19.1).
  18 #   RANLIB: archive index generator (since dpkg 1.19.1).
  19 #   PKG_CONFIG: pkg-config tool.
  20 #   QMAKE: Qt build system generator (since dpkg 1.20.0).
  21 #
  22 # All the above variables have a counterpart variable for the build tool,
  23 # as in CC → CC_FOR_BUILD.
  24 #
  25 # The variables are not exported by default. This can be changed by
  26 # defining DPKG_EXPORT_BUILDTOOLS.
